Pages not showing content

I’m writing my own theme for WordPress 2.6.2… having a dilly of a time getting some basic functionality to work. I’m not new to wordpress or PHP, but I am new to creating a theme from scratch.

So here’s the deal… I’ve got styles.css, index.php, and page.php (among others). When I load my site, my index shows fine, my header displays all the Pages I’ve created. However, when I click on any of my nav links to go to a Page, I get a 404.

The Pages all have content, so I can’t figure out why I’m getting a 404. page.php consists of:

<?php get_header(); ?>
THIS SHOULD SHOW UP WHEN I TRY TO LOAD A PAGE
<?php get_sidebar(); ?>
<?php get_footer(); ?>
